CLC 2300 overheating

[geraldrobins]

My son has a clc cl2300,53 reg with the 1800cc engine. The cooling warning is on but the radiator is full. In slow moving traffic the car will overheat and if it gets too hot it will cut out presumably due to safety feature. It would seem that the fan is not operating.
Any advise please and can anyone recommend a good independent in the Lambour/Hungerford area.
Happy New Year to all.

It may be the fan control unit. If like the W203 cars? The fan control is built into the fan shroud in the bottom N/S corner. It can fill up with crud. See if you can get the shroud out easily and look for water/crud ingress. It may clean out.

Check the pipes to see if they are warming up and the coolant circulation is running as it should. You might have a blockage somewhere.
